Help, can't figure this out

try plumbing everything in pvc-i don't like the look of your return line-no clamp to hold your line-i also think it would be better not to have ridges in your line.i agree with using 45s instead of 90s

K so I see that you already have a ball valve in the return line from the sump to choke back the pump if necessary.....try to make sure that all drain and return lines are running at a gradual down slope towards the sump, no ups and downs in the lines for air locks. umm for your drain line to the sump, if there are any 90's in the lines try to see if you can switch to 45 degree elbows instead so that water flow doesnt get slowed down too much on the way from tank to sump....also I noticed that you are using 1/2 hose for the return line when there is a 1 inch return bulkhead soo im wondering if you ended up doing the same on the return line. Did you take that 1 1/2 inch bulkhead there and slap a 1 inch hose on it for the drain? if so....dont, try to get some plumbing that matches the 1 1/2 inch bulkhead for the drain so that way you have maximum flow rate available to you for the drain. Your return line is fine for the way the hoses are except the one bend in the hose there, but the drain line may need some work on it.
